Abstract
A method of fabricating a light emitting device includes (i) determining whether each measurement location is defective or not based on a measurement result of the emission wavelength of each location, (ii) forming a test stacked structure by combining one of the first wafers, one of the second wafers, and one of the third wafers in a set of wafers, and (iii) calculating a combination yield of the test stacked structure based on a count of defective measurement locations that overlap in the test stacked structure.
